How 3D Printing is Disrupting Dentistry

3D printing is bringing a smile to many Dentists’ due to its high accuracy, reliability, reduction of turnaround time and the improvement of services. Stereolithography (SLA) printing uses an optical system to cure resin, accurate to a tolerance of ± 35 microns. The printer converts a digital 3D model into paths that a laser will then trace layer by layer into a resin bath. The laser cures the resin, converting the digital model into a physical object within a few hours.

The key uses of 3D printing with Dentistry include:

  • Highly Accurate Dental and Orthodontic Models
  • Castable Crowns, Bridges and Partial Denture Frameworks
  • Direct Crowns and Bridges in Four Shades
  • Bite Splints or Night Guards
  • Indirect Bonding Trays
  • Surgical Drill Guides
  • Denture Bases

With the drastic reduction in the price and increase in quality of SLA printers, it has become the perfect tool for Dentists. Such models are helping to reduce cost and save in production time. In conjunction with 3D scanning, a detailed model of a patients inner mouth can be produced in half the time of a typical orthopaedic model.

The desktop 3D printer by Formlabs, uses three types of materials engineered for dental application: Dental SG Resin, Dental LT Clear Resin and Standard Grey Resin. Dental SG Resin is Class 1 biocompatible and autoclavable; designed to accurately and repeatedly produce crown and bridge models with removable dies, with an accuracy much higher than the acceptable clinical limit. Furthermore, Dental LT Clear Resin is Class IIa long-term biocompatible, which has a high resistance to fracture and wear; making it well suited for hard splints, retainers, and other direct-printed long-term orthodontic appliances. Standard Grey Resin can be used for a range of uses, including; orthodontic, diagnostic, and educational models, as well as for vacuum-forming aligners or other appliances. When used with a clear separator, Grey Resin can also be used to quickly produce retainers.
